Stars Reach is Raph Koster's 30-year dream MMO — and it's nothing like World of Warcraft

Raph Koster, the veteran designer behind Ultima Online and Star Wars Galaxies, has unveiled Stars Reach, a new MMO he describes as the game he has wanted to make for 30 years. Built by his studio Playable Worlds, the project traces back to a pitch Koster originally made as a follow-up to Ultima Online in the late 1990s — only now, he says, has the technology finally caught up to the ambition.

Stars Reach spans thousands of planets connected by wormholes that can appear and disappear over time, making entire regions of space temporarily inaccessible. The simulation runs deep: every cubic meter of every planet carries temperature, humidity, geology, and hundreds of material properties. Rain falls, rivers carve terrain, lakes freeze in winter, forests burn, and cave ceilings can collapse from overmining. Players can melt stone into lava, cool it into new rock formations, or accidentally trigger ecological disasters. Beyond the environmental systems, the game supports mining asteroids, terraforming landscapes, building cities, crafting starships, running businesses, performing as entertainers, establishing governments, or just exploring. During a demo, Koster showed a player-built settlement of 78 citizens who had elected a mayor, zoned public parks, and built a transit system — none of it designed by Playable Worlds, all of it sanctioned and constructed by players.

Koster is deliberately positioning Stars Reach against the WoW-shaped mold that has dominated the MMO genre for two decades. He argues that World of Warcraft, while phenomenal, narrowed the possibility space for what MMOs could be — and that every other genre then stripped away the remaining distinctive features MMOs once had. His broader point is philosophical: MMOs aren't a game genre, they're virtual places in which you put games. Koster also credits the MMO space with originating live services, community management, subscription models, and microtransactions — tools the entire games industry now uses. Stars Reach is his attempt to reclaim that original, wider vision of a persistent world built around emergence rather than scripted progression.

No release date or platform details were announced alongside the reveal. The demo suggests a game still in active development, but one with an unusually clear creative vision behind it — and a designer who has been waiting three decades to build it.
